Lower Back Pain: Common Causes and What Actually Helps

Almost everyone gets lower back pain at some point. For most people it is unpleasant, it settles within a few weeks, and it does not mean something is seriously wrong. For a smaller group it keeps coming back, and that is where the useful work happens.

This page covers what commonly causes lower back pain, what the evidence says actually helps, and the specific symptoms that mean you should see a clinician rather than manage it yourself.

Most lower back pain has no single cause

This is the part that surprises people. In the majority of cases, scans and examinations do not identify one structure responsible for the pain. It is described as non-specific low back pain, which sounds unhelpful but is accurate: the pain is real, but it is rarely a case of one disc slipping out of place.

That matters because it changes what to do. If the problem is not a single broken part, the answer is usually gradual return to normal movement rather than rest and protection.

Common causes and triggers

• Muscular strain. Sudden lifting, twisting, or an unfamiliar movement. Common and usually short-lived.
• Prolonged sitting. Long hours in one position, particularly in a car or at a desk, leave the hips and back stiff and the supporting muscles inactive.
• Sudden increase in load. Carrying something heavier than usual, or a long drive after months of short ones.
• Age-related changes. Discs lose height and joints become arthritic over decades. These changes are common in people with no pain at all, which is why a scan finding is not automatically the cause.
• Nerve irritation. When pain travels down a leg, with numbness or tingling, a nerve root is involved. This is sciatica, and it is assessed differently from ordinary back pain.
• Stress and sleep. Both influence pain perception and how quickly people recover. They are not imaginary factors.

Why driving is hard on the back

Driving combines three things: a fixed seated position, whole-body vibration from the road, and a seat shaped for the average body rather than yours. Over a long shift, the small stabilising muscles around the spine work continuously to hold you upright, and they fatigue.

There is no single posture that prevents this. What helps is changing position regularly, supporting the lower back so it does not have to hold itself up unassisted, and getting out of the vehicle.

• Seat angle. Recline slightly rather than sitting bolt upright. The hips should be slightly higher than the knees.
• Lumbar support. A small cushion or rolled towel in the curve of the lower back, not a large pad that pushes you forward.
• Distance to the pedals. Close enough that your knee stays slightly bent, not locked straight.
• Breaks. Every hour where possible, even two minutes standing and walking.
• Getting out. Turn, place both feet on the ground, then stand, rather than twisting and swinging out in one movement.

What actually helps

Stay active. The strongest and most consistent finding in back pain research is that staying active beats bed rest for ordinary low back pain. Complete rest beyond a day or two delays recovery.

Walk. Short frequent walks are the easiest way back into movement. Start with ten minutes and build.

Build strength gradually. Once the acute phase settles, training the muscles around the hips and trunk reduces the chance of recurrence. Slow, controlled movements rather than heavy loading:

• Glute bridge — lie on your back, knees bent, lift the hips, lower slowly. 3 sets of 10.
• Dead bug — on your back, lower one arm and the opposite leg while keeping the lower back still. 3 sets of 8 per side.
• Bird dog — on hands and knees, extend one arm and the opposite leg, hold two seconds. 3 sets of 8 per side.
• Sit-to-stand — stand from a chair without using your hands. 3 sets of 8.

Our home workout with no equipment covers these movements in a full routine, and the desk exercise guide covers what to do during a working day.

Sleep and stress. Poor sleep and sustained stress both make pain harder to manage. Neither is a cure, but both are worth addressing if the pain keeps returning.

What does not help

• Prolonged bed rest. More than a day or two makes recovery slower, not faster.
• Waiting for the pain to disappear before moving. Movement is part of the treatment, not something to do afterwards.
• Braces as a permanent solution. A support can be useful for a specific aggravating task, short term. It does not strengthen anything, and wearing one all day lets the muscles that should be working do less.
• Inversion tables and traction devices. Evidence is weak, and they carry risks for some people.
• “Posture correction” gadgets. There is no single correct posture, and devices that hold you in one position do not fix the underlying issue.
• Painkillers as a strategy. They can take the edge off, but they do not address the cause. Ask a pharmacist before using them regularly, and never exceed the stated dose.

Symptoms that need a clinician, not a guide

Most back pain is manageable at home. These are the exceptions, and they need medical assessment promptly:

• Numbness around the groin, inner thighs or buttocks, or difficulty passing urine or controlling your bladder or bowels.
• Progressive weakness in one or both legs.
• Fever, chills or unexplained weight loss alongside the back pain.
• Severe pain that wakes you at night and does not change with position.
• Pain after a fall, collision or other significant trauma.
• Back pain with a history of cancer.

These are uncommon, but they are the reason a page like this cannot replace an examination.

If you want a support while you work

A back brace can make a long shift more comfortable by holding the lower back in a supported position, and some people find it useful for a specific task such as loading or a long drive. It is a comfort measure, not a treatment, and it is not a substitute for strength work.

We stock two: an adjustable back brace and an adjustable back brace with mesh straps. Both are elastic supports with adjustable closures. They do not correct posture, and we do not claim they do. Our back support buying guide covers fit, sizing and when not to wear one.

Frequently asked questions

How long does lower back pain last?

Most episodes improve substantially within two to four weeks, though mild symptoms can linger longer. Recurrence is common, which is why strength work matters.

Should I rest or keep moving?

Keep moving gently. Bed rest beyond a day or two slows recovery. Avoid heavy lifting briefly, not all activity.

Do I need an X-ray or MRI?

Usually not for ordinary back pain without red flags. Scans commonly show changes in people with no pain, which can lead to unnecessary worry. A clinician decides when imaging is useful.

Is driving bad for your back?

Long shifts in a fixed position are a common trigger, but driving itself is not damaging. Seat setup, breaks and strength work make the difference.

Does a back brace weaken your muscles?

Wearing one all day lets the supporting muscles do less work. Used short term for a specific task, that is not a concern. Used permanently instead of training, it is.
